"Kanche" got unanimous positive response from all circles, but the film has its own share of flaws. While the film is set in World War II backdrop in 1940s, how come they have quoted Sri Sri's quotes that were published in 1950?
Inside the film, Dasu, played by Srinivas Avasarala, always mentions some quotes written by Srinivasa Rao who will be understood as Sri Sri by anyone. The allegation is that, when Sri Sri released those prose and poetry in 1950 as "Maha Prastanam" book, how come a film set in 1940 backdrop will reprise them. "Dasu is a friend of Kompella Janardhan Rao a very close friend of Sri Sri garu. Director Krish wouldn't make such a mistake", says Varun Tej. For that reason, Dasu character in the film never addresses him as 'Sri Sri' but only as Srinivasa Rao.
Probably no other Telugu director would have thought to such extent while making a Telugu movie, and we have to appreciate Krish in that context.
